Trainer Paul Magnier hit out after his well-backed runner Golan Go finished unplaced in the Derrinstown Stud Apprentice Handicap.

The four-year-old was backed into 8-1 from 20s for the one-mile-six-furlong heat but he became very upset in the stalls, with rider Tim Carroll exiting the saddle before the horse tried to duck under the front of the stalls.

Golan Go was passed fit to race after trotting up at the start but his original stall had been damaged and he was forced to start on the far outside of the field.

He totally missed the break but stayed on to finish seventh behind 6-1 shot Binocular leaving Magnier thoroughly dissatisfied.

"He was punch-drunk and not surprisingly left when the race got underway," said the handler.

"I'm not blaming the vet or the starter as they only did their job but my horse was at a huge disadvantage.

"From an integrity point of view, the betting public is not protected. He actually broke the gate and he shouldn't have run."< Beau Michael booked his ticket for the Galway Festival with a six-length romp in the Martin Tyrrell Auctioneers Handicap.

Winning trainer Adrian McGuinness said: "Galway is the plan, for the amateur handicap on the Monday and he could run again on the Thursday in the two-mile-one-furlong novice chase."< Myrine a half-sister to Group One winners Sagamix and Sagacity, lost her maiden tag with a wide-margin success in the Paddy Smyth Memorial Maiden.

The four-year-old cost 240,000 guineas as a yearling back in 2007 and she finally repaid a small slice of that price with victory on her second racecourse start.

"She has her winning bracket now. We'll see how the handicapper treats her," said Ger Flynn, representing winning trainer Jim Bolger.

Father and son team of Tony and Danny Mullins struck gold as Monthly Medal ran out a three-and-a-half-length winner of the Blue Thunder Fast Foods Claiming Race.

Mullins senior said: "He's in again at Leopardstown on Thursday. I'd like to go to Galway too over seven furlongs or a mile."
